The fix was simple yet crucial: using INPUT_PULLUP instead of INPUT. This enables the Arduino’s internal pull-up resistor, which keeps the input pin in a known HIGH state when the button is not ...

Arduino Button-LED Project This is my first Arduino mini-project. It turns an LED on when a button is pressed, using a digital input pin.

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

The nunchuck is meant to plug into a Wii controller and the connection is I 2 C, so that’s trivial to interface to an Arduino or other small microcontroller. The only issue is making the connection.

The Adafruit Gemma measures just 1 inch in size and is powered by an ATtiny85 and programmable with an Arduino IDE over USB, allowing you to create those wearable projects of the future.

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...
